A 0.3 kg bead slides on a curved frictionless wire, starting from rest at point A, where d=1.5 m. At point B the bead collides elastically with a 0.8 kg ball at rest.

A) Find the speed of the bead at point B just before it collides with the ball.
B) Find the speed of the ball just after the collision.
C) Find the maximum height of the ball rises at it moves up the wire.
